The bookstore keeps an inventory of the books it sells. The listing includes details such as author, title, price, publisher and stock position. Whenever a customer wants a book, the seller enters the title and author, and the system searches the list to see if it's available or not. If this is not the case, a corresponding message will be displayed. If so, the system will display the book details and the requested number of copies. If copies are requested, details of the book and requirements for the number of copies requested. If the requested copies are available, the total price of the requested copies will be displayed; otherwise the message ?The requested copies are not in stock? is displayed. Design the system using a class called book with appropriate member functions and constructors. Use the new operator in constructors to allocate the required memory space. Implement a C++ program into the system

A book shop maintains the inventory of books that are being sold at the shop. The list includes details such as author, title, price, publisher and stock position. Whenever a customer wants a book, the sales person inputs the title and author and the system searches the list and displays whether it is available or not. If it is not, an appropriate message is displayed. If it is, then the system displays the book details and requests for the number of copies required. If the requested copies book details and requests for the number of copies required. If the requested copies are available, the total cost of the requested copies is displayed; otherwise the message?Required copies not in stock? is displayed. Design a system using a class called books with suitable member functions and Constructors. Use new operator in constructors to allocate memory space required. Implement C++ program for the system.
